The TPS54424EVM-779 is an 4-A synchronous converter evaluation module (EVM). The TPS54424 is a synchronous buck converter, integrating both power MOSFETs to minimize solution size and provide high efficiency at full load. Fixed-frequency peak current-mode control is used to minimize period and on-time jitter. Forced continuous conduction mode keeps the switching frequency fixed at light loads and enables fast transient response to and from light loads.
